I was pleasantly surprised when I removed my new Leecraft CR-4 insert from its package. I was impressed by how smooth and accuratly machined it was. With only a slight adjustment it fit nice and tight. It is by far the BEST insert I've ever seen. From: JACK

Use MicroJig MJ Splitter Kits for added table saw safety. Available in THICK or THIN kerf they are easily installed and simple to align. Not for use with Leecraft inserts that already have the riving knife slot cut in. Intended for inserts WITHOUT the riving knife slot.
